Phil, I'm not an aerobatic pilot or a female, but Svetlana Kapinina in the video has a five way seat restraint harness and what looks like a parachute harness under that. If they're tightened up correctly, that should do the job of any sport bra.

It would be good to see no. 2 fly after gathering dust over all those years.
Before their fall out in 2014, there were plans to build new An-124's as a joint Ukrainian/Russian venture with the plant to be located in Russia. That went by the wayside and now the Russians are looking into building them on their own. Problem is that the Antonov plant was moved from Russia to Ukraine in the 50's, and after the breakup of the Union, it became Ukrainian property along with all the documentation and patents. Ukraine is now saying that they will take legal action if necessary to stop Russia from building the 124.
As the world economy grows, there would probably be enough work for two 225's.

News item on Iran's new Kowsar fighter.
It looks very F-5 like, most likely the Saeqeh re-designed back to the original F-5 tail. I'd assume it has a lot of Russian and/or Chinese components and systems. The bang seats in the video appear to be a Russian K-36D variant.
Just guessing for the engines that they would have a stock of GE J85 ECU's from their Northrup F-5's.

Peter, that was the Zveno project. I guess at that stage it had a limited future with in flight re-fueling just round the corner.
I think that one in your photo at the Monino Air Force Museum is the only survivor.
Cheers, Willie.
